Abstract

Through harvesting of the increased Stokes shift of CdS QDs via Cu-doping, the concentration-quenching or aggregation-quenching of CdS QDs was largely alleviated. A dually-enriched strategy with both polyvinylpyrrolidone (PVP) twisting and SiO₂ loading was developed for generating a highly luminescent doped-dots (d-dots) assembly for improved cell imaging.
